Comparison-adjusted CMF
-
For both SMF and CMF, a value below 1 indicates improvement (crash reduction for SMF and cost savings for CMF), and a value above 1 indicates deterioration.
The tables below summarize severity-level predicted crash frequency SMF and predicted cost CMF for the before and after periods.
